Thisinvention relates new anduseful improvements in" at dental slab.

' The invention has: for anobjectrthe con struction of a'dentalslabwhich isichar acterized by a funnel like cavity on'the top extending to one side, and said sidebeing formed with a recess of substantially Us shape, forming two projections atthe mouth 10 of 'the cavity so that" chemicals from. the

slab maybe readily replaced into the bottle from which they arertaken' and placed on the slab. z v 'A still furtherfobject: of. thisinvention is to arrange'the cavity ofthe recess upon one.

corner of the slabfl Another'oneaof the objects of this inven-- tion is to provide adjustable sections on the slab adapted to be moved for theipurpose of changing the size of the recess toaccommodate bottles having different sizedjnecksi A still further object of this invention is the 'fconstruction of an-"article ofthe class described which is of simple durablecon operation and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the inventionare more particularly set forth. 7

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a perspective view of a dental slab constructed according to this invention.

Fig. 2 is an edge elevational viewof Fig. 1.

Fig. 3 is a plan view of a portion of Fig. 1.

Fig. 4 is a perspective view showing the slab tilted as though in a position to replace the chemical fromit into a bottle.

Fig. 5 is a fragmentary perspective view similar to a portion of Fig. 1 but illustrating amodification.

Fig. 6 is a sectional view taken on the line 66 of Fig. 5.

Fig. 7 is a fragmentary perspective view looking in the direction of the line/(+7 of Fig. 1.

Fig. 8 is a longitudinal secti nal view taken on the line 8-8 of Fig. l. i r The dental slab, according 'tothis invention, comprises material 10 in the formof a;- dental slab and having a funnel-like cavity 11 on the top surface extending toone 'side of the slab and terminating in a discharge end 12. A recess 13 is formed in the side of the slab so -as' to form projections '14 on opposite sides of the discharge end 12. The

recess '13 is'of substantially U shape so that the slab may be tilted as for example shown in 4;, when the materialon the slab is replaced-'- into the bottle.: The"rim offlthe neckfof the'bottlewillengageintothearms 55 V of the U-shaped recess "13 so that the proj ections '14 extend past the 'rimi and. allow proper discharge from the funnel: shaped cavity'into the bottle, a I f? Another funnel-like "cavity lode-formed on the top surface of the dental slabnear. one corner and hasa 'discharge end :Idtermin'ating in the-corner. A substantially U-shaped recess 17 is formed. on the. corner ofthe slab in-a manner so that a pairof projections are formed which are on opposite sides of the discharge 16. Thearms 19*.from the'lui-shaped' recess are disposed on different sides1of-the slab in a manner sorthatilwhen therslab is tilted from the horizontalltoaid 'in'the discharge of material back into a bottle, the rim of the bottle may engage within the arms 19'to insure thatthe' pro ections 18 extend slightly into-the neck .of the bottleiand. thus guide the dischargefromathe funnelelike cavity. In Figs. 1, 2 and 3 the dot and-dash lines indicate a a bottle placed vbeneath the projections 14: in a position before the slab is tilted upwards as shown in Fig.4.;- Another cavity 15 is shown with a vertical: groove 15*.on the side of the dental slab. A- circular groove 15 is providedlunder groove15?, in the bottom face of the slab 1Q,v toposition the'neck of the bottle.

. The cavity 11 may be oneitherfaceofthe 9 slab 10;or on bothxfaces at the opposite'edges, sozthatthe slab may be reyersed and either 7 facemay be used.. 1 --=:In;;Figs. '5 and 6 an arrangement has been disclosed in which provision;hasbeenamade 1 form the other sides of'tlie arms or th ...U'--

V tongues 22 engageable in slots formed in the a fications coming-,wiithinthe-scope of the in for adapting the dental slab, according to this invention, to bottles having necks of dif ferent diameters. Examining Fig. 4,' it will be seen that if the diameter of the top of the neckof the bottle is too large, the slab will not be able to be tilted so that the arms of the U-shaped recessengage the rimpfthe bttl6.x Accordingly the slab is provided With sections which are adjustably mounted. The inner sides 21 of the sections 20 shaped recess. Each of the sections 20 have slab 10 so that the sections 20 may beadjusted laterally. only. Screws 23' engage through: slots 24in the" sections so as to adjustably holdfl the' sections in positions; Should it-be desirableto increase the width ofthe: lzlshapedl recess, the screws 23 i should beloosenedand th'e sections 20 movedaway fromeachvothen;v 7
